Trio™ Operating Instructions
CAUTION:
Inaccurate SpO
2
measurements may be caused by:
•
incorrect sensor application or use
•
significant levels of dysfunctional hemoglobins, (e.g.,
carboxyhemoglobin or methemoglobin)
•
intra-vascular dyes such as indocyanine green or
methylene blue
•
exposure to excessive illumination such as surgical
lamps (especially ones with a xenon light source),
bilirubin lamps, fluorescent lights, infrared heating
lamps, or excessive ambient light. In such cases, cover
the sensor site with opaque material.
•
excessive patient movement
•
venous pulsations
•
electro-surgical interference
•
placement of a sensor on an extremity that has a blood
pressure cuff, arterial catheter or intra-vascular line.
•
nail polish or fungus
CAUTION:
In certain situations in which perfusion and signal strength
are low, such as in patients with thick or pigmented skin,
inaccurately low SpO
2
readings will result. Verification of
oxygenation should be made, especially in preterm infants
and patients with chronic lung disease, before instituting
any therapy or intervention.
CAUTION:
Many patients suffer from poor peripheral perfusion due to
hypothermia, hypovolemia, severe vasoconstriction,
reduced cardiac output, etc. These symptoms may cause a
loss in vital sign readings.
CAUTION:
If the sensor or patient cable are damaged in any way,
discontinue use immediately. To prevent damage, do not
soak or immerse the sensor in any liquid solution. Do not
attempt to sterilize.
CAUTION:
When equipped with Masimo SpO
2
, use only Masimo
oxygen sensors and cables. Use of other oxygen sensors
may cause improper oximeter performance.
CAUTION:
When equipped with Nellcor SpO
2
, use only Nellcor oxygen
sensors and cables. Use of other oxygen sensors may cause
improper oximeter performance.
CAUTION:
When using the Trio equipped with SpO
2
, use only
approved supplied oxygen transducers and Patient Cables.
Use of other oxygen transducers may cause improper
oximeter performance.
CAUTION:
Use only approved blood pressure cuffs and hoses with the
Trio.
CAUTION:
Please consult a physician for interpretation of blood
pressure measurements.
CAUTION:
A blood pressure measurement can be affected by the
position of the patient, and his/her physiological condition
as well as other factors, such as patient movement.
